Abstract
A lumen woven support (), comprising a netted tube body () woven by weaving filaments (), wherein the netted tube body () comprises a first portion () and a second portion () along an axial direction; the netted tube body () further comprises a plurality of first hooked and wound knots (), at least two weaving filaments () from one end of the second portion () are hooked and wound to each other in the axial direction of the netted tube body () to form a first hooked and wound knot () and are then separated, and all the weaving filaments () constituting the first hooked and wound knots () are woven to form the first portion (); and the mesh density of the first portion () is smaller than that of the second portion (). In the above-mentioned lumen woven support (), since the mesh density of the first portion () is smaller than that of the second portion (), the radial supporting force of the first portion () is reduced, and the stimulation to a normal lumen wall caused by the first portion () is reduced, thereby lowering a risk of restenosis. In addition, the first portion () has a good flexibility, the second portion () has a greater radial supporting force so as to provide sufficient anchoring, and therefore, the above-mentioned lumen woven support () is applicable to practical implantation.
